Representatives from the World Resources Institute, the U.N. Environment Program, and others announced a report, Building the Climate Change Regime: Survey and Analysis of Approaches October 24, calling for greater ambition in local, national, and international efforts to combat climate change. The report suggests a number of ideas to complement the annual U.N. Conference of Parties with other efforts to boost clean energy use and reduce GHG emissions, including raising climate issues in other bodies such as the Group of 20 economic forum.
